FILLER-CONTAINING FILM
20210238456 · 2021-08-05 · ·

A filler-containing film that holds fillers and a fine solid in an insulating resin layer and a predetermined arrangement of the fillers is repeated as viewed in a plan view has a proportion of 300% or less where the proportion is a repeat pitch of the fillers after thermocompression bonding to that before thermocompression bonding during thermocompression bonding under a predetermined thermocompression bonding condition with the filler-containing film held between smooth surfaces. A method of producing the filler-containing film includes the steps of: forming an insulating resin layer on a release substrate; pushing fillers from a surface on a side opposite to the release substrate of the insulating resin layer; and layering the insulating resin layer containing the fillers pushed and another insulating resin layer. This filler-containing film suppresses disorder of arrangement of fillers during thermocompression bonding of the film to an article.
